enhance data points to a figure created by gridfit

Hello,
I am using the gridfit file to my topographical data ((x,y,z) scatter
point data). It works well - thanks the good code. But I would like
to enhance data points in x,y plane or on the top of the surface
marked, for examples, circles. I do not manage to do that. I only get
a new figure.
Have anyone had this kind of problem? I would be pleased for any
piece of advice.

If you are getting a new figure,
then you want to use the hold
command after you plot the surface.
Something like this...
surf(X,Y,Z)
hold on
plot3(xdata,ydata,zdata,'o')
hold off

Create image from data pointsI have a function that creates an ellipse giving me an (x,y)
coordinate for each ellipse data point. I want to turn the (x,y) data
into an image "matrix" such that imshow or image will display it. The
(x,y) data does not fall onto integer pixel locations. Is there a
function that converts from scattered (x,y) data into an image? I
want to be able to create an ellipse image in the same format as if I
captured a picture of an ellipse with a camera and read it in.
Thanks...Tom

Editing figure data points (not manually)I have some figures with too many data points plotted, but not the actual data. I'm looking for some means to reduce the number of data points on the figure (by a factor of 10). Is there any efficient way to do it than first extracting all the data and then re-plotting?
Thanks!

Hey 7, was it 50 million data points, or was it 500 million data points?This is related to your financial system in which you claimed to have
"graphed every transaction across the globe." <belly laugh!>
March 2009: "I had a small project last week to play with 50 million
data points and I coded up all that in a few hours."
July 2010: "I can assure you micoshaft products could not touch the half
billion odd data points with open sourced software."
Which? Show us some proof of either number. Or slink away as usual.

creating a function for 3D data points.hello all i would like to find out if anyone can help me.
i understand that polyfit can be used to fit data in 2 dimensions
(x,y).
is there any way or function that can help to fit 3 dimension (x,y,z)
data.
i have looked at meshgrid, and griddata, but all they do is just mesh
for me, and thats all.
what i really need is to be able to come up with a function that i
can use as a path contraint, i have learnt to use parametric
equations for 3d object such as cylinder and cones, but what i would
really like to be able to do, is to create a 3d object in 3d drawing

Creating a 3D image from the 3D data pointsI have a dataset of 3D "grayscale" images (medical ultrasound dataset) in the form of cartesian coordinates of each voxel and according grayscale intesity values.

I have seen a similar function but for "plotting" named "pcolor" for "2D" images. I want that the output be a "3D" image "matrix", so this function is not useful.

get spefic data points from plot figureHello,
I am wondering if there is an interactive way of being able to
select, copy, look at selected data from a plot figure?? I have
plotted the full data set but only need specfic points that can
easily be extraced by looking at the plot figure.

Extracting single point data from matlab figureI'm sure this is a simple problem, but i can't think how to do it.
In one figure i have the derivative of a function. I can use "min" to extract the y-value at at minimum point on the figure, but how do i get the corresponding x-value for the given y-value from this figure?
Cheers,
Alex.

? create 3d obj from external data pointsHi:
FemLab allows users to load external data files containing points to
create their own complicate objects. However, its command "loft" requires
points on each 2D curves to be the same. Yet, I don't find a command
to make the imported points on each 2D curve to be the same. How do
I solve this? I tried the following script but did not pass because I did
not put points on each curve the same.

Hi Thad
If you have loads of free disk space on your 810 then your method is
fine but if not you may consider Simply FTPing or iSeroes Access file
transfering the files directly from the iSeries files to Windows Text

Turn off the data points in a figure with fig-terminalHello, dear NG,
I've got a plot from a file to fig terminal. When I draw it with p3d
on the x11 terminal, then everything looks fine.
unset surface
set pm3d at s .
But if I
set terminal fig metric color
set output "test.fig" ,
then the data points appear in the plot in red colour (as '+'
symbols). How do I get rid od the them?
Could someone help, please?
Thank you very much in advance!

Hi marcv,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; When I open your VI it's broken and the error seems related to this term in a formula node:
Y=5*X^4
Try:
Y=5*pow(X,4)

Re: Creating a new dataset by adding some data pointsWhat about the following:
The goal seems to be somewhat which has several sums of several banks, but
all for each month.
Suggestion:
bring all the bank data together by month. Each loan, expenses, ... get the
name of the bank in the variables:
loan_bank1=
expenses_bank1=
asset_bank1=
....
the only comman variable is DATE (or MONTH, or...)
After that you merge the 4, 5, 6 (or n) datasets BY DATE.
You have a dataset with all the numeric values for each bank. So you can
calculate all the combinations of banks, you might want and a total.
If there are 56 banks, you could also use arrays to g...

How to export Saved figure data points to Matlab work space?Hello.
I have a saved matlab figure. I want to have the Y-axis data points and X-axis data points in the work space. for example assume I have already plotted y=2x for x=1:1:100. now I only have the saved figure. how can i extract x=[1:1:100] and y=[2:2:200] from that saved figure? Is there any solution to do so?

I have one more question for you.
My actual bank # (Bank_ID) data is a numberic format rather than a
character format. Hence, I was getting the below error message. Is there
any way that I can use a numeric format with $BMERGE? Or do you know any
function/command does the same job for a numeric variable?

numeric variable Bank_ID.
